Korea's Commercial Lease Protection Act: What Every Tenant Must Know

If you operate a business in a rented commercial space in South Korea, the Commercial Building Lease Protection Act (상가건물임대차보호법) is your most important legal shield. It guarantees lease renewal rights, protects key money, and caps rent increases — but many tenants don't fully understand their protections.

Key Protections at a Glance

Protection	Details	Key Point
Lease renewal right	Request renewal for up to 10 years total	Limited grounds for landlord refusal
Key money protection	Landlord liable for damages if blocking recovery	Tenant can introduce successor
Rent increase cap	Maximum 5% per year	Regardless of market conditions
Fixed date certification	Obtained from tax office	Priority repayment right
Opposing power	Business registration + possession	Survives ownership changes

10-Year Lease Renewal Right

Tenants can demand renewal for a total period of 10 years from the original lease start date. This is the cornerstone of business stability protection.

When Can a Landlord Refuse?

1. Tenant defaulted on rent 3 or more times
2. Tenant sublet without consent
3. Building destroyed beyond repair
4. Landlord needs the space for personal use (strict requirements)
5. Tenant's material breach of obligations

Renewal requests must be made 6 months to 1 month before lease expiry. After 10 years, no renewal right exists — negotiate directly.

Key Money (권리금) Protection

What Is Key Money?

Key money is compensation for the tangible and intangible business value of a commercial location — equipment, customer base, brand reputation, and location premium.

Type	Covers
Facility key money	Interior, equipment, fixtures
Business key money	Customer base, revenue, goodwill
Location key money	Foot traffic, area premium

Prohibited Landlord Actions

Landlords cannot obstruct key money recovery by:

1. Refusing to contract with a tenant-introduced successor (without cause)
2. Imposing unreasonable conditions (excessive rent demands)
3. Contracting with a third party, ignoring the tenant's successor
4. Leaving the space vacant without justification

Violations result in liability for the full key money amount.

Rent Increase Cap (Maximum 5%)

Situation	Cap Applies?
Lease renewal	Yes — 5% cap
Initial contract	No — free negotiation
Re-contract after 10 years	No — free negotiation
Tacit renewal	Yes — existing terms maintained

Common Disputes and Solutions

Dispute	Core Issue	Response
Renewal refusal	Landlord claims personal use	Demand proof of genuine intent
Key money obstruction	Excessive rent to deter successors	Sue for damages
Excessive rent increase	Above 5% cap	File for mediation
Deposit non-return	Unpaid after lease end	Lease registration order + lawsuit

Dispute Resolution Channels

1. Korea Legal Aid Corporation: Free legal counsel (call 132)
2. Commercial Lease Dispute Mediation Committee: Formal mediation
3. Court litigation: Final resort

Sharing Lease Terms Securely

Commercial leases remain effective for up to 10 years, making secure document management critical. When discussing sensitive terms — rent amounts, key money, special conditions — sending via a KakaoTalk group is risky.

Use LOCK.PUB to create a secure memo with key contract terms, set a password and expiration time, and share safely:

• Only authorized parties can view
• Auto-deletes after expiration
• Minimizes leak risk

Send the password via a separate channel (phone call).

Key Takeaways

Korea's Commercial Lease Protection Act provides strong tenant safeguards:

1. 10-year renewal right — business continuity
2. Key money protection — fair compensation for business value
3. 5% rent cap — predictable cost management
4. Fixed date + opposing power — deposit protection

Keep your contract safe. Record negotiations. When sharing sensitive lease terms, use LOCK.PUB password-protected memos.
